  dist: change tar format default to ustar.
  
  Suggested in https://bugs.gnu.org74847.
  
  * m4/init.m4 (tar-ustar): make ustar the default instead of tar-v7.
  * doc/automake.texi (tar-formats): document this.
  * NEWS: mention this.
  * t/tar-override.sh: force tar-v7 for purposes of this test.

  # Check that the user can override the tar program used by "make dist"
  # at runtime, by redefining the 'TAR' environment variable.
  # 
  # Currently this works only when the tar format used is 'v7';
  # as of 2025 (automake-1.18), this is no longer the default,
  # so force that format in our test setup.
